Diversity of Living Things Flashcards
What are the three concepts that examine the definition of the term ‘species’?
Morphological, Biological, and Phylogenetic Species Concepts
What is the Systema Naturae?
A system by Carolus Linnaeus using the ranks of: Domain, Kingdom, Phylum, Subphylum, Class, Order, Family, Genus, Species
What is Taxonomy?
A system of classification of all organisms using binomial nomenclature (Genus and Species).

The branch of biology that deals with the structure (/form) of organisms
What is Anatomy?
The branch of biology that deals with structure and form including internal systems (not function)
What is Physiology?
The branch of biology that deals with the physical and chemical functions including internal processes (structure/shape/function)
What is the Phylogenetic Tree?
The phylogenetic tree shows the evolutionary relationships between different species
What are the three domains?
Archaea, Bacteria, Eukarya (Eukaryote)
What are prokaryotic cells?
No membrane-bound nucleus with simple internal cell structure, usually smaller.
What are eukaryotic cells?
Cells with membrane-bound nucleus and complex internal cell structures. Usually larger up to 1000x.
What are the 6 different kingdoms?
Animalia, Plantae, Archaebacteria, Eubacteria, Protista, Fungi
What are the three important ways of studying biodiversity?
Genetic Diversity, Species Diversity, Ecosystem Diversity
What is a virus?
It is a non (not considered truly) -living organism that cannot create its own energy or reproduce on its own, requiring a host cell to replicate and is otherwise dormant.
What are the two lifestyles of viruses?
Lytic Cycle, Lysogenic Cycle
